To do a Ganesh Puja at home for Ganesh Chaturthi, start by cleaning your home well to welcome Lord Ganesha. Decorate a special place with flowers and lights. Get a clay idol of Lord Ganesha, which is eco-friendly and can be immersed in a plant later. Put the idol on a raised platform with a new saffron or orange cloth. Begin the puja by washing the idol's feet with holy water and giving it a panchamrit bath. Offer five flowers at the idol's feet and do padya and samarpan rituals. Dress the idol in new clothes and decorate it with sandalwood paste, durva grass, sindoor, garlands, and sweets. Say prayers and chant mantras, and end with the aarti "Jai Jai Ganesh, Jai Ganesh Deva." Offer 21 sweets like modaks and ladoos to Lord Ganesha. This puja is done to seek blessings and happiness from Lord Ganesha during this special festival.
